State-of-the-art in cutting performance and surface integrity considering tool edge micro-geometry in metal cutting process

Tool edge preparation is preferred in metal machining processes, which is strongly related to process reliability, tool cutting performance and surface integrity. Therefore, proper edge micro-geometry optimization and selection could be taken as a feasible approach to improve tool cutting performance, slow tool wear and ameliorate surface integrity. This review paper addresses the recent development in tool cutting performance (including cutting forces, temperature and tool wear), surface integrity (including surface geometrical characteristics, metallurgical behaviour and mechanical property) in the metal cutting processes considering the cutting insert with various designed micro-geometry. In addition, the prospective research issue and tool technology development in this field is also presented.
